Migrate iOS plugin to Swift Package Manager

[elitree]

Context

CocoaPods is entering maintenance mode toward the end of the year, and Flutter now provides first-class Swift Package Manager support along with documentation for plugin authors on migrating. This PR adopts SPM ahead of that transition so the plugin keeps working smoothly as the ecosystem moves off CocoaPods.

Summary

Adds Swift Package Manager (SPM) support to the iOS plugin following Flutter's recommended dual-support approach — the plugin now ships an SPM package and keeps a working podspec, so it builds whether or not the consuming app has SPM enabled. No breaking changes for existing CocoaPods users.

Changes

Plugin

• Restructured iOS sources into the SPM layout (history preserved via git mv):
  • ios/Classes/OpenFilePlugin.m → ios/open_filex/Sources/open_filex/OpenFilePlugin.m
  • ios/Classes/OpenFilePlugin.h → ios/open_filex/Sources/open_filex/include/open_filex/OpenFilePlugin.h (public headers under include/)
• Added ios/open_filex/Package.swift — Objective-C target with .headerSearchPath("include/open_filex"), swift-tools-version: 5.9
• Updated ios/open_filex.podspec to point source_files / public_header_files at the new paths (CocoaPods still works)
• Bumped iOS deployment target 8.0 → 13.0 (Flutter's current enforced minimum)
• Added .build/ to ios/.gitignore

Example app

• Xcode project updated with the FlutterGeneratedPluginSwiftPackage reference and deployment target → 13.0
• .gitignore gained .build/ and .swiftpm/
• Includes the Flutter UIScene-lifecycle project migration (AppDelegate.swift, Info.plist) that Flutter applies on build — kept intentionally so the example builds cleanly on current Flutter

Testing

• flutter build ios --simulator --no-codesign passes with Swift Package Manager enabled; build log confirms "Adding Swift Package Manager integration" and the plugin resolves through Package.swift.
• CocoaPods path remains intact via the updated podspec.

@elitree Any Update?

@javaherisaber please migrate the iOS plugin to Swift Package Manager (SwiftPM) as soon as possible.

Flutter has now made Swift Package Manager the default approach for managing iOS/macOS native dependencies starting with Flutter 3.44, while CocoaPods is being maintained mainly for backward compatibility. Flutter is also recommending that plugin authors add SwiftPM compatibility as soon as possible.

This migration will help ensure compatibility with upcoming Flutter versions and avoid future dependency/build issues related to the legacy CocoaPods-based setup.

Please prioritize the migration when possible.

Use
https://pub.dev/packages/open_app_file
instead of this pkg
